Subject: Query regarding pseudo nmi support on GIC V3 and request_nmi()
Date: Thu, 7 May 2020 21:36:19 +0530	[thread overview]
Message-ID: <2a0d5719-b2c7-1287-e0b5-2dd8b1072e49@codeaurora.org> (raw)

Hi,

I have one query regarding pseudo NMI support on GIC v3; from what I 
could understand, GIC v3 supports pseudo NMI setup for SPIs and PPIs.
However the request_nmi() in irq framework requires NMI to be per cpu
interrupt source (it checks for IRQF_PERCPU). Can you please help
understand this part, how SPIs can be configured as NMIs, if there is
a per cpu interrupt source restriction?



Thanks
Neeraj
